'enslavement-advocating' originates from the combination of 'enslavement' and 'advocating', where 'enslavement' refers to the act of making someone a slave, and 'advocating' means to publicly support or recommend a particular cause or policy.

'enslavement' comes from the word 'enslave', which evolved from the Old French 'enslavir', and 'advocating' comes from the Latin 'advocare', meaning 'to call to one's aid'.

Initially, 'enslavement' meant 'the act of making someone a slave', and 'advocating' meant 'to call to one's aid'. Over time, the combination has come to mean 'supporting the practice of enslavement'.
